Pulldown Fileds TransferRate Help!!!

[Del Chapple]

alot of stuff there.. why noy transfer to 24p?

“IMPORT: Should I import the secuence at 59,94 or at 29,97 ? fields or no fields ? Upper or lower ?
If I am not wrong I should not import the seq with fields because it is 59,94i to get the fields in DPX images.”

1080i 29 is the same as 1080i 59 (Sony is counting frames-Panasonic counting fields).. Fields Yes Top/upper for HD Interlace. If there are hybrid frames the dpx seq will have them also.

“PULLDOWN: Is it really necessary to remove pulldown if I am working with masks ? How will I put pulldown again for render? Just in render settings?
What happen with frame rate after pulldown ? Will I work in a slower frame rate during my work and I will make the correct frame rate again for output render? ”

Interlace will be harder to work with, can you cut in 24p or 23.98p ? 23.98p when you cross convert adds a pulldown so your deliverable is at 29.97.

“RENDER: AFter all this , which frame rate should I use to render the final DPX sequence? The same as I have received it ? 59,94i If I do in this way I imagine that the project where it will be imported it will be 29,97 or 30i so the scene will played correctly with fields. ”

Really i cant say it enough 24p!! interpret the footage and remove the pull down..

you cant hear my inner voice scream… can you..?

del chapple (del…) :

It’s not my decision how to transfer it . First of all the footage must be edited and the transfer is at 30i.

They have offered me to shoot the effects footage at 30 fps but there are some others that have been already shooted and they were shooted at 24 and transfered to 30i.

My big problems is that after rendering my tests I still see the huge jaggy edges in playback even in interlaced monitor.

That’s why I am trying to investigate the whole process to see where it’s wrong.

Dave:

Thanks for your explanation.
Now…

What about import ? Should I import the sequence in 59,94 or 29,97 ? with or with no fields ?

Is there any chance that neither of the 5 pulldown choices work well ?

Is it ok that I will never see nice edges in my pc monitor because I will never see interlaced it ? I see horribly jaggy edges when I have a fast movement like a car crossing on cam.

If I will work with mask, should I keep the double frame rate in COMP to work with fields ? 47.952

Thanks

Dave ok I get your point.

Just what I have read is that DPX seq don´t have video information so I have to define the frame rate to import.
My dpx seq as I have told is inside a folder that is named 59,94i. So will I import it at 29,97 upper ?

If I will deliver dpx seq with fields, should I render it at double frame rate ? So to have 29,97i will I render it at 59,94?

Sorry if I am misunderstanding things. I am new on this field.

Thanks

Dave:

Is there anyway for me to send you or upload 3 or 4 sec of this material ?? I think that something could be wrong in the original dpx sequence.

How could I do to send it to you ?
